Title: A press train for the production of sheet-metal parts
IPC: B21D22/00
Filed: 1961-08-10
Abstract: 945,264. Stamping presses. MASCHINENFABRIK WEINGARTEN A.G. Aug. 10, 1961 [Aug. 16, 1960], No. 28891/61. Heading B3Q. A press train comprising a sheet metal drawing press and any desired number of metal working presses is characterized in that the drawing press operates continuously while the working press or presses operate intermittently and gripper rails for conveying the workpiece are driven or controlled by the drawing press. The press train comprises a drawing press 1 and metal working presses 2 and 3. The sheet holder slide 4 of the drawing press operates downwardly and a drawing slide operates upwardly. Each press has its own drive that of the drawing press being situated beneath the press as at 9 and that of the other presses at the head of each press as at 10 and 11. Gripper rails 12 and 13 for conveying the workpiece through the press train are driven from cams on the crankshaft 14 of the drawing press, Fig. 4. A cam 15 determines the forward and reverse movements of the rails, a cam 16 the close and open movements and a cam 17 the lift and drop movements. The cam 15 operates a slide 18 and a rack 19, movable in guides 20 and 21. The rack engages a gear-wheel 24 which, through various gearing on shafts 25, 28, 31 and 36, reciprocates drive slides 43, attached to the gripper rails 12 and 13 and arranged on either side of the drawing press. A disengaging coupling 32 enables the forward-reverse movement of the rails to be stopped whilst setting up the machine tools. The cam 16 actuates a push-rod 44 constructed as a stepped piston and having a rack 46 engaging a gear-wheel 48 which through linkwork mounted on shafts 47, 52 and 57, opens and closes the gripper rails. The cam 17 actuates similar linkwork for lifting and lowering the gripper rails. The close-lift-move forward-lower-and open movements of the gripper rails are performed during the movement of the sheet-holder slide of the drawing press and the reverse movement of the rails is performed whilst the sheet-holder slide is stationary.

Title: Improvements in or relating to wooden railway sleepers
Inventor: HOFER MARC
IPC: E01B9/16
Filed: 1954-10-08
Abstract: 751,341. Wooden railway sleepers. SIDERVIA SOC. ANON. Oct. 8, 1954, No. 29036/54. Class 104 (2). A wooden railway sleeper 1 has truncated conical hardwood dowels 3 fitted in the areas receiving sleeper screws 6 or other clamping devices with the interposition of a layer of an adhesive in the holes 2 in the sleeper 1. Grooves 4 are provided on the outer surface of the dowel 3. The holes 2 in the sleeper may be arranged so that the minor diameter of the cone is at the top or bottom of the sleeper 1, thus enabling the dowel to be inserted from the bottom or top of the sleeper 1. The dowels 3 may be cut-away at their upper ends at 9 to accommodate the foot of the rail 7. Adhesive squeezed from between the mating surfaces of the dowel 3 and sleeper 1 form fillets 5 thus prevent water entering between the mating surfaces. The rail 7 may rest directly on the sleeper 1 or on a hardwood saddle 10 held laterally.in position by the dowels 3 and stuck to the sleeper 1. Alternatively, the saddle 10 and the dowels 3 may be formed as a single moulded wood unit. The rail 7 may be held in position by the .screws 6, Fig. 1, or by a resilient member 12 inserted therebetween with one end resting on the foot of the rail 7 and the other end engaging a recess 11 formed in the saddle 10. A grooved rubber pad 13 may be inserted between the rail 7 and the saddle 10.

Title: Improvements in or relating to electric timer switches
IPC: H01H43/02
Filed: 1961-08-11
Abstract: 983,572. Time switches. CONTROLS CO. OF AMERICA. Aug. 11, 1961 [March 6, 1961], No. 29071/61. Heading H2B. The starting position of a rotary timer is set by manual rotation of a switch cam-shaft 20 until a spring-loaded stop pin 32 enters a selected hole 60 in a plate 62; the shaft is them pushed axially to disengage the pin from the plate and to close the supply switch 26 to a synchronous motor 16 which drives the camshaft for the selected programme. The pin 32 is carried on a disc 28 and co-operates with one of a number of holes 60 on a laterally movable plate 62. The plate 62 is moved by depressing a selected one of the push-buttons 75, each of which moves the plate 62 a different distance such that a different hole 60 lies in the path of revolution of the pin 32. When a button 75 is depressed a tongue 82 (Fig. 6) engages an associated cam slope (Fig. 9, not shown), in a plate 86 which is thus moved a specific distance laterally and a rack thereon turns a gear 87 rigid with gear 91 to move a rack 94 and plate 62 through an amplified distance. Plate 62 is accurately located by a tongue 96 entering an associated notch 98. Only one notch 98 can be aligned with a tongue 96 at a time and hence simultaneous operation by more than one button 75 is prevented. The push-button assembly is provided with the usual plate (Fig. 9, not shown), for latching a depressed button and releasing the previously depressed button. The initial movement of this latch plate retracts the stop-pin 32 (so that it will not interfere with the setting movement of plate 62) by camming rearwardly a retractor 44 (Figs. 6 and 7), pivoted at 46 on disc 28, its free end engaging a collar integral with pin 32. Axial movement inward of shaft 20 after rotation to the start position also depresses retractor 44. At the end of a selected programme one of the tabs 30 or disc 28 will be aligned with a cam 45 on the mounting plate (Fig. 7) and any attempt to rotate shaft 20 causes the tab to ride up on the cam, forcing the shaft outward, thereby ensuring that switch 26 is opened.

Title: Method of regulating anode-cathode spacing in an electrolytic cell and apparatus therefor
IPC: G05D3/12
Filed: 1973-06-19
Abstract: 1430161 Automatic control of electrolysis OLIN CORP 19 June 1973 [17 July 1972] 29078/73 Heading G3R [ Also in Division C7] Voltage and current density measurements in a liquid cathode electrolytic cell are combined to form a quantity which is compared with a,reference value to derive a difference signal. If this signal lies outside a given range, the anode-cathode spacing is adjusted and the measurements are repeated. As shown, the spacing between anode sets 9, 12 in electrolytic cells 10, 13 and their respective liquid cathodes is adjusted by motors driven by an automatic control unit 6 in response to selected current and voltage measurements. Terminals 14, 15, 17, 18, 20 along conductors 8, 11 are used to supply the current and voltage signals to amplifiers 27, 28 when appropriate relay contacts 21-26 are closed. Thermistor circuits 16, 19 provide temperature compensation. The amplifier outputs are connected to hold circuits 37, 38 through isolating and noise eliminating circuits 29-36. A selector unit 39 passes required signals through an A-D converter 40 to the control unit 6. The current and voltage measurements may be used in a number of different ways. In one method, a voltage coefficient is calculated by subtracting the electrolyte decomposition voltage from the measured electrode voltage and dividing by the current density. The resultant value is compared with a standard coefficient, and deviations outside a predetermined range cause the anode-cathode spacing to be adjusted. The actual signals used may be the averages of a series of current and voltage measurements made over a given time period. The calculations may be performed by a digital computer. In other embodiments, the measured current may also be compared with a predetermined desired range of values to produce a control signal, average current fluctuations over a period of time may be calculated, and each of a series of current readings may be compared with a respective preceding measurement.

Filed: 1954-10-14
Abstract: 764,981. Multi-stage washers. SIMONCARVES, Ltd. Oct. 14, 1954, No. 29657/54. Class 81(1) A washer for treating an aqueous solution with a solvent of lower density than the aqueous solution, for the removal of the solute by the solvent, comprises a number of washer compartments in each of which the solvent is intimately mixed with the aqueous solution, means for allowing layers of solvent and aqueous solution to separate and flow in opposite directions to adjacent compartments, and means for withdrawing aqueous solution and solvent from a compartment and intimately mixing them before returning them to the lower part of the same compartment. As shown the untreated aqueous liquor enters bay 2 of a washer comprising a tank a divided by a partition b into eight bays 1 to 8 of which bays 2 to 7 are contact bays, bay 1 is for the collection of solvent, and bay 8 for the washed liquor, by pipe c and flows by gravity through the washer via interconnecting pipes d to bay 8 from which it flows through a pipe f, via a vented overflow box e. The solvent enters at No. 7 bay through a pipe g and flows to bay No. 1 over the tops of partitions b, the heights of which fall progressively from bay 8 to bay 1, whence the rich solvent is withdrawn from an outlet h. The liquor and solvent are mixed within each bay of the washer by aspirating liquor through a pipe i to a recirculating pump and feeding it back to approximately the same position through a pipe j in which there is an injector k which aspirates solvent through a pipe m from the solvent separated layer of the same bay, into the flow of liquor re-entering the bay. The injector produces very small droplets of solvent which due to the difference in gravity flow upwards and the height of the washer is such that these droplets have sufficient contact time whilst flowing through the liquor layer. The liquor and solvent may alternatively be contacted in each bay by taking off by independent pumps, a sufficient quantity of solvent from the upper solvent layer and intimately mixing this in a separate mixing chamber using a high speed rotating vane with a separate quantity of liquor taken off several feet from the base of the same bay and returning this well dispersed solvent in liquor back to the lower half of the same stage.
